hi,
i installed the solaris 10 11/06 x86 on the first partition of IDE primary master, the parition is set active for boot, i customized the layout to 2 slices one the / 14 GB and other the swap 1300 MB, the installation process completed to 100 % but in the last hanged with this error message:
installing boot information:
-Updating boot enviroment configuration
-Installing boot blocks (c0d0)
-Installing boot blocks (/dev/rdsk/c0d0s0)
connot open/stat device /dev/rdsk/c0d0s2
ERROR: installboot (1M) failed
ERROR: could not install boot blocks
then i added the solaris to the fedora grub menu.lst:
title solaris
root (hd0,0)
chainloader +1
makeactive
after booting to solaris from the gurb the error was:
Booting solaris
root (hd0,0)
File system type unknown, partition type 0xbf
Error 13: Invalid or unsupported excutable format

ok, then i put the solaris dvd boot to singe user mode mount the system under /a and run the instalgrubl command in the shell:
/sbin/installgrub -m /boot/grub/stage1 /boot/grub/stage2 /dev/dsk/c0d0s0
The error was:
Cannot open/stat device /dev/dsk/c0d0s2
then i run the command again as:
/sbin/installgrub -m /boot/grub/stage1 /boot/grub/stage2 /dev/dsk/c0d0
then the error was:
raw device must be a root slice (not s2)
please help what to do next to boot the solaris?
